"PYPEWRITING MACHINE.

Application filed August 26, 1921, Serial No. 495,679 Renewed septecmber 11, 1924.

To all whom it may concern:

Be it known that I, Join: VV'ALDHEI a citizen of the United State's, .residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful. Improvements in Typewriting Machines, of which the following is a specification. r

A This invention relates to continuous billing .typewritin J machine one form of which is shown in t e patent to Wernery and Smith,

N 0. 1,132,055, dated March 16', 1915,, and in which a pack of coutinous webs may be fed from a source of supply over a rearward extension of the typewriter-carriage and between interleaved carbon-sheets of a carbondisplacing carriage, the sheets being led around the platen to the printing point. The webs are usually provided with printed forms or billheads disposed in sets lengthwise of the pack, the forms being filled in by the typewriting'maehine; After a set of forms has been typed, the carbons are first shifted ordisplaced prior to severing or tearing off a set of printed forms. -To enable this to be done, the platen may be raised to a position to allow the straightening out of the webs, so that the carbon maylbe'freely displaced by pushing the carbon-carriage rearwardly; thus taking the carbons to a new set of forms, and at the same time the webs may be drawn forwardly to a stop to gage the length of said forms. After thisis done, the platen may be lowered to its typing position, and the printed forms may then be severed by a suitable knife' The adjacent webs of the pack are joined to each other by folds at their side edges. The folded "edges may be perforated so, that the various forms may be readily separated from each other, after severing a set of forms from vthe pack. The perforations, however, leave a ragged edge which distracts from the general appearance of the bill. Due to this fact, the users of the fan-fold webs sometimes trim the side edges "of the @pack before introducing it into the machine. This .is 7 objectionable, however,

- since the separate sheets tend to creep relatively to each other in the operation of feeding them around the platen whiletyping the forms. It is, therefore, desirable to triiu the side edges of the webs after they have been inserted in the machine, and thus prevent cumulative creeping of the sheets relatively to each-othr.

p In my pending application, No. 448,047, filed February 26, 1921, I have provided for this purpose two relatively fixed cutters, one at each side of the web, and mounted on the carbon-carriage, so that the edges may be trimmed by said cutters during a carbondisplaei-ng operation.

An object of this invention is to provide rota-table cutters on the carbon-carriage to trim the edges of the web, said cutters'being geared to a rack to be rotated as they move rearwardly with the carbon-carriage, the peripheral speed of each cutter being greater than its bodily movement.

Another object of the invention is to provide guiding means which may comprise a pair of flat bars, toprevent the edges of the web from leaving the cutters while said edges are being trimmed.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional side view of a typewriter-carriage and the rearward extension thereof upon which the carbon-carriage travels backand forth relatively to the platen. v

Figure 2 is a sectional front View, on a somewhat reduced scale, showing the relation between the pack of webs and the cutters,,the section being taken on the line 22 of Figure 1.

Figure 3 is a fragmentary top plan view of the rear part of Figure 1.

Figure 5 is a detail View of the gearing for the cutters, showing the driving rack disposed to rotate each cutter in an opposite direction to that in Figure 1.

Figure 6 is a slightly modified form of the invention, ih which a single set of cutters is used. V

Type-be rs 10 may swing upwardly and rearwardly to print against the front face of a platen 11, mounted in a carriage 12 to travel back and forth on the main frame (not shown) of an Underwood typewriting machine. To the carriage 12 is connected a rearward extension or table 13 comprising a front bar 14 and a rear bar 15 connected to each other by side bars 16, the rear bar having upwardly-extending arms 17 to support a guide-bar 18, over which a continuous ack 20 of webs or work-sheets 21 may be ed from any suitable source of supply. The Webs are led forwardly to a guide-bar 22 on the carriage and then downwardly around the platen 11 to the printing point at the front 'of the'platen. The webs are then uided upwardly behind the usual knife'23, 5y which portions thereof may be severed from the pack 20. The separate plies or webs of the pack are each connected to its adjacent one by folds 24 (Figure 4), and the webs are interleaved in the usual way by carbon;sheets 25 secured to carbon-carrying 20 bars 26 on a carbon-carriage 27. The carboncarria e is mounted on tracks 28 secured to the si e bars 16 of the rearward extension, so that it may move freely forwardly with the webs as they are fed around the platen and be moved rearwardly to shift-the carbons to fresh portions of the webs, as hereinafter pointed out. Side guides 30 are provided on the rear guide-bar 18 and guides 31 on the guide-bar 22 of the carriage to prevent lateral displacement of the pack of sheets relatively to the platen, The various webs are joined by the folds 24 at their side edges, as above stated, to prevent cumulative creep of the sheets relatively to each other, which occurs when feeding a pack of separated sheets around the" platen.

The webs are usually provided with printed forms, thus forming superposed sets.

After a set of forms has been typed, it is desirable to shift the carbon-sheets relatively to the pack of webs to a new set of forms,

before the typed forms are severed. To enable this to be done, the platen is mounted in a frame 35, which may be swung about a shaft 3.6 on the typewriter-carriage to raise the platen, and'thus permit the webs 21 to .be straightened out, so that the carbon-sheets may b freely moved rearwardly' by pushing the carbon-carriage 27 by means of a handle .37. During the carbon-displacing operation,

' the pack of sheets may also be drawn forwardly until arrested by the usual stop or gage (not shown) "with which the leading edge of the typed forms may engage so as to position the typed forms at their tearing ofl" positions. After the carbons have been displaced and the forms gaged, the platen may 1 be lowered to its typing position and the typed forms may then be severed from the pack by means of the knife 23.

In the patent to Jesse A. B. Smith, No. 1,206,765, dated November 28, 1916, there are provided slitting devices on the carbon-holders to sever the sheets along their side ed es as the carbon-carriage is moved rearwardly side of the pack 20 of sheets, the cutters being secured to ashaft 42 mounted in cars 43 of brackets 44 extending rearwardly from the carbon-carriage 27, the distance between the cutters being slightly less than the width of the pack of sheets, sothat the edges of the pack maybe trimmed as the carbon-carriage is moved rearwardly during the carbon-displacing operation. The cutters 41 may be opposed by another set of co-operating cutters 45 mounted beneath the pack of sheets and secured to a shaft 46 also supported'by the ears 43 of brackets 44. K

The cutters may be driven so that their peripheral speed may be greater than'their bodily movement. For this purpose, the two shafts 42 and 46 are connected to each other by gears 50 and 51, and the lower shaft 46 has secured thereto a pinion 52 meshing with a rack 53 fixed to one of the side bars 16 of the rearward extension by suitable brackets 54. It will be seen that the rack 53 may be disposed above or below the pinion tively, to cause the cutters to'rota'te towards or away from the webs.

to the cutters 41 and 45, there maybe provided an upper guide-bar 55 and a lower guide-bar 56, between which thepack is fed, the lower guide-bar 56 being secured to extensions 57 of the brackets 44 on the carboncarriage. The upper guide-bar .55 isheld in place by screws 58 extending upwardly from the lower guide-bar 56, and is pressed against the lower guide-bar by suitable springs 60, the tension of which may be adjusted by nuts 61. To prevent the pack of sheets from moving si'dewise at the cutters, there maybe provided side guides 62, which may be formed on rearward projections 63 of the lower guide-bar 56.

To prevent the shavings 40 of the edges of To guide the pack of. sheets horizontally by which it may be directly connected with the carbon-carriage 27, anda side-guide 62" extends upwardly at each end of the bar 56.

improvements may be used without others. 7
